What RPM Do You Drive At

Like i said, rev it at 5000rpm all day long if thats what does it for you, but all youre doing is creating extra wear, burning gas, and making you look like a complete jackass to bystanders. if you are so desparate to hear the noise from the pathetic m96 while cruising, then have at it.

Everyone warms up their car’s engines, except those who do not ever start them. How you warm up is the difference.

What RPM do you drive at?...........The title should be "At what RPM do you drive?" Never end a sentence with a preposition.
There.........a useful contribution to the thread.

I'm not even sure we can agree on what is "high" and what is "low".
Personally I would consider 4000-5000 "medium/moderate" rpms. 3000 or less "low" rpms, and above 6000 "high" rpms but I get the feeling there would be a lot of disagreement around here. ( once again on my M96 987S with MT) I don't know where I got those numbers. never analyzed anything. Just my driving "feel" regarding the car.

I should be clear about letting car warm up
My statement was vague, so I will explain what I meant.
I usally wait until I can see temp gauge move the needle off the bottom.
Then I drive, but I keep rpms under 3500, until operating temperature.
I know that cold running puts a lot of unburnt gas in the oil.
It is also, true that running your car at operating temperatures, for a continued period of time, the unburnt gas in the oil will be burnt in the combustion chamber.
It is also true, there is a reason why we run synthetic oil like Mobil 1, that will protect our cylinders during a cold start.

How does Mobile 1 protect M96 cylinders in cold start? Don't all oils drain into the pan after shutdown? Isn't the correct viscosity for the season what will protect the cylinders at cold start?

Still too long warm up IMO. Start, wait for RPM's to drop and go while maintaining lower (3K) revs until operating temp reached.

For folks driving their cars regularly, like every day, there is hardly any metal to metal contact on startup due to oil sticking to surfaces from the day before. Those driving their cars once a month will suffer more wear from each cold start because much of the oil would have made its way off the surfaces.

I don’t think you mean ‘ don’t warm up,’ but rather, ‘warm up by driving it, being careful not to use prodigious amounts of throttle and RPMs during warmup.’
Everyone warms up their car’s engines, except those who do not ever start them. How you warm up is the difference.

How long does it take for your RPMs to drop? My Mk1 starts up and revs immediately to 2k within the first 1-2 seconds and then stays at 1000-1100 for at least 1-3 minutes. I do not wait longer than 5 seconds to start driving. I see no reason to wait for the secondary air injection to stop and for engine to ultimately settle down to 675, which is where my car idles when hot without the AC on (800 with the AC on).
Yes but some oils stick to surfaces better than others. I don’t know about Mobil 1.
